Wildfire responders continued to tackle the Nimrod fire burning between the Beavertail and Bearmouth areas on Friday.
The fire could be seen from Interstate 90 near the Beavertail exit, though authorities are asking people not to stop and look at the fire.
Fire officials estimate the fire has burned roughly 350 acres, and say the cause of the fire is under investigation, though one fire official told NBC Montana the cause is reportedly a downed power line.
Winds of up to 20 mph reached the blaze at around 3:00 p.m. on Friday, presenting challenges for crews as they worked the blaze in rugged terrain. Fire officials say one Hot Shot crew is on the ground at the fire.
Officials say the fire is burning pine and grass, and the wind has been pushing the blaze eastward, away from structures. As of Friday evening, no structures were at-risk and no evacuations were initiated.
Responders at the fire include the Deer Lodge Fire Crew, Blackfeet Type 2 Crew and Idaho Panhandle Hot Shots. Several aerial resources and dozers were also utilized Saturday.
